BOOK-SUPPORT FOR CHAIRS. i

4SIEECIFIC'JION tbrming' part Of Letters Patent No. 723,144, dated. March 17, 1903. Application tiled July 22,1902. Serial No. 116,546. (No model.)

To a/ZZ, whom, t may concern.-

Be it known that I, THADDEUS DoNoHUn.,ofV

j lo ofthe character stated designed to be used as an attachment to arm-chairs. 1

The invention involves special details of [construction and combination of parts, all as will be hereinafter fully described, with the i novel featnrespointed out in the claims.

In order to enable others to make and use my invention, Iwill now proceed to describe its construction and use, reference being had to the accompanying drawings, which formV "zo a part of this specification, and in'which- Figure l is a perspective view illustrating my invention in use. Fig. 2 is a detail sectional view showing means for securing my book-support to the chair-arms; and Fig. 3 is a modified and'enlarged sectional view, the section being taken on lines x of Fig. 1.`

In carrying out my invention I Aprovide a table A, having a ledge BV at its lower edge,-

as shown. t The table A is supported by a pe- 3o culiar frame consisting of a bar C a length substantially that of ledge B and a bar D,

` having iiattened ends E, adapted to rest upon the chair-arms, as shown in Fig. l of theV drawings. The bars C and D are connected by end cross-pieces F F and two centrally-located and elongated cross-pieces G G, spaced apart just far enough to receive the brace or leg H, extending from the chair-seat up to and between two cleats I on the under side 4o of the table.- The upper end of the leg H may be fashioned conforming to the angle of table and its lower end provided with an adjustable foot J, adapted in its adjustment to lengthen or shorten the said leg, as may be desired. The foot J is provided with an elongated slot through which projects a clamping-bolt L, xed to the leg H, and the foot is guided by a pin M on the leg above the bolt L, (see Figs. l and 3,) which enters 5o the upper part of the slot K. The cleats I and also cleats N on the under side of the table A are ixedly secured to the bar C and,

with the leg H, provide bracing for the table. It is understood that the leg H should be secured to the cleats I and the projecting ends ofthe crosspieces Gand pins O, or other suitable means may be employed to that end.

In my drawings I have shown the chair-arms provided with pins or knobs P, serving to prevent forward sliding ot the support, and as providing additional securing means show a strap Q, passing around the chair-arms and the ends of the bar D. Such means, however, the pin or knob P andthe straps Q, may be dispensed with without aecting or detracting from the utility of my invention.

The leg H is designed to rest upon the chairbottom, as shown in Fig. l, and in addition to providing support for the table A it may 4be clamped between a persons legs-,and thereby aord means for holding the book-support "in place uponl the chair-arms. i

When it is desired to change the inclination .ot the table A, the same may be accomplished -by adjusting the foot J, as hereinbetore described, which obvionslylengthens or shortens the leg H.

The construction shown in Fig. 3 involves a slight modification whereby the inclination of the table A may be changed when. it is desirable not to shorten or lengthentlhe leg H after being adjusted according to the height otuthe chair-arms In the modied form the pin O is movable in a slot O2, formed in the leg H, and the table A has pivotal movement To permit the pivotal move-` on the pin O3. ment of the table just described, the upper end of the leg H is made rounding, as shown in Fig. 3.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. A chair attachment of the character described `having a tablewith means .adapted i for supporting it, the said supporting means consisting of a bar ixed to the table and having its ends adapted to rest upon the chairarms, and a brace extending down from the under side of the table adapted to rest upon the upper side of the chair-bottom, the said brace being formed of two parts secured together and adapted to be adj usted lengthwise substantially as described.

2. A chair attachment of the character described having a table with means for sup- .sideof the table adapted to rest upon Ithe porting it, the Said supporting means consistchair-bottom, the said brace having 1ength ing of a projecting bar fixed to the lower or wise adjustment substantially as described.
